Title: Rotary coupling system for transferring radar signals - uses light source modulated by electrical signals and associated with photocell
Inventor: SPINNER GEORG DIPL ING DR ING
IPC: H04B10/00
Filed: 1977-04-15
Abstract: The rotary electrical signals coupling system is used for transferring radar signals. It has a light source modulated by the electrical signals and thereby conveying their information between the stator and rotor. The light source may be located in the rotor or the stator or both: the light detector is located in the other part of the coupling and reconverts the light into electrical signals. Light guides may be employed.

Title: Support for furniture flap - has strut which slides against fixed stud which engages in recess for locking
Inventor: KING WILHELM
IPC: E05C17/14
Filed: 1977-05-04
Abstract: The supporting strut (for a furniture flap (12) has a spring-loaded pivoted mounting (17) on the flap. The lower edge of the strut slides against a stud (14) on the furniture wall as the flap is raised. When fully raised, the spring (18) presses the strut (20) downwards so that the stud is engaged with a recess (22). To release the strut, the flap is raised slightly. The stud rides over a triangular sliding cam (30). The flap is then lowered and the stud pushes the cam (30) to the limit of its travel, so that the stud rides up the oblique cam surface and is thus disengaged from the recess.

Title: Automatic food processing control - by microprocessor receiving temp. and humidity inputs
Inventor: PAKULA ERWIN
IPC: A23B4/052
Filed: 1977-06-04
Abstract: In a processing system for food, such as meat and sausages, on a large scale, thermometer probes measure the actual temperature of the material, the dry and wet bulb tempertures in the process chambers in the successive operations. After conversion to digital signals, a microprocessor adjusts the process parameters until the desired values are reached. The humidity is calculated from the dry and wet bulb thermometer readings and displayed continuously. The full automation by microprocessor eliminates human errors in operation and in reading. The quality of the food produced is improved and process supervision has been simplified to relieve the operating personnel.

Title: Tomograph appts. with controlled radiation source intensity - has control achieving roughly constant quantum flow per unit of displacement of radiation measuring appts. during its sideways movement
Inventor: KRUMME HANS-JOCHEN DIPL ING
IPC: H05G1/34
Filed: 1977-06-24
Abstract: The tomograph appts. uses a radiation source producing a beam whose cross-sectional spread, perpendicular to the layer plane, corresponds to the strength of this layer. The radiation receiver, behind the patient, records the intensity of the projected beam. A drive for the measuring section alternately rotates and pushes sideways the radiation measuring appts. in the layer plane for scanning of the subject in various directions. The signals from the radiators receiver are converted to provide the tomograph. The intensity of the source is made dependent upon the speed of operation of the radiation measuring appts. The control is such that a roughly constant quantum flow per unit of displacement is achieved during the sideways movement.

Title: Blowdown device with immersed condensation tube - esp. for boiling water reactor has perforated pipe cone or rings
Inventor: KUEHNEL ROLAND
IPC: G21C9/012
Filed: 1977-07-21
Abstract: A blowdown device for limiting excess pressure in a nuclear power plant under fault conditions is intended esp. for a boiling water reactor and consists of one or more condensation tubes having their lower ends immersed in a water pool, their upper ends being connected to the source of steam or steam-gas mixture. The lower, discharge end of the tube is equipped with an inbuilt component throughout its length which has a number of overflow edges for the cooling water in the pool. The pressure and water level fluctuations inside the tube caused by the condensation process cause water to flow over these edges, so that a sprinkling or spraying action provides a large thermal exchange surface between the water droplets and the steam. Increased cooling surface resulting from the splashing action and increased turbulence of the cooling water provide effective rapid heat transfer between steam and water and thus a relatively uniform rate of condensation. In addition, sub-atmospheric pressure waves may cause air to be drawn into the steam space, thus still further reducing the structural loading consequent upon steam pressure.

Title: Baseband data transmission system for cable links - describes one binary state with lower-amplitude frequency and other with higher-amplitude second frequency
Inventor: LUDWIG VOLKER DIPL ING
IPC: H04L27/32
Filed: 1978-05-30
Abstract: The data transmission system has the binary states of its data described by two frequencies that experience no phase jump when the binary state changes. The amplitude of the lower frequency is less than the amplitude of the upper frequency to reduce distortion.
